I have a 2023 Subaru Crosstrek that has the annoying auto stop/start to "Save Fuel". I installed an aftermarket auto stop/start eliminator. It has worked perfectly over the last 7 months. Two weeks ago, the Subaru app indicated there might be a potential problem with the Eyesight Driver Assist Technology. the message came up twice while the vehicle was not in use. So, I presume that it cleared before we went to drive the vehicle. The eliminator is still in use and not giving any errors. Is there any way the auto stop/start eliminator cause an issue with the eyesight system?

Is there any way the auto stop/start eliminator cause an issue with the eyesight system?
Yes. The electronics in modern vehicles are very sensitive and all the modules are interconnected and can affect each other. Installing a 3rd-party device of that type, which may well be poorly engineered and manufactured, can potentially cause all kinds of problems.
How would it work perfectly fine for seven months, then start?

Cheap components degrading after seven months causing problems for the car's electrical system. Or a poorly-designed device taking time to gradually inflict damage to the car's electronics. Not all flaws manifest themselves immediately.
Or it could be entirely coincidental. You asked if it was possible, and it is, but there's no way to tell if it's the proximate cause in this case. As a practical matter however it is a bad idea to connect random devices to your car that affect computer modules as this one would have to do in order to disable automatic start/stop.
